The Lowdown
Alright, Rusty here again. Let’s break it down for Costeño Beach.
This is a beginner-friendly beach break, exposed and consistent, welcoming that NE swell. The real highlight is the Saturday session, especially the afternoon. We’ve got a 7ft NE swell with a 9-second period, and the combined energy is 571 (moderate). But the best part? Saturday afternoon goes glassy – zero wind. That’s the kind of clean, smooth surface that makes a good swell turn into a great session. The water’s at 84°F, which is about normal for the time of year.
The lead-up is a mixed bag. Thursday the 10th is a washout – cross-on wind, marginal surf. Skip it. Friday the 11th is better. The morning has a light cross-on, but the afternoon goes glassy with 5ft of NE swell. It’s a bit short period at 8 seconds, but it’s a clean option if you’re itching. Saturday morning the 12th has 7ft swell but with a light cross-on, so a bit of chop. The afternoon is the gold.
Sunday the 13th is a letdown – cross-on wind, period drops to 7 seconds, energy falls to 342 (moderate). From Monday the 14th through Wednesday the 16th, we’re looking at 4ft down to 4ft, short period, mostly marginal. A few glassy afternoons, but the swell is weak and energy is low (under 200). Not much happening.
After the 16th, it’s a long slide into small surf. From the 17th onward, we’re talking 4ft down to 2ft, periods of 6 to 8 seconds, and combined energy dropping from 270 to just 21 (weak). There are glassy afternoons, but the waves are too small and weak for a proper paddle. This is a nearly week-long stretch of flat to tiny surf. By the 25th, it’s barely a ripple.
The only standout in this whole 16-day window is that Saturday afternoon, the 12th of September. That’s your best bet. The rest is a waiting game.
Rusty.

A general guide to surfing at Costeño Beach can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Costeño Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
